Types of ROOTS Blowers

ROOTS blowers, also known as rotary lobe blowers, come in several types, each designed to meet specific industrial needs. Here are the main types:

**1. Standard Two-Lobe ROOTS Blowers

• Design: Features two counter-rotating lobes.
• Operation: Moves air by trapping and displacing a fixed volume with each rotation.
• Applications: Common in pneumatic conveying, vacuum systems, and wastewater treatment.

**2. Three-Lobe ROOTS Blowers

• Design: Uses three lobes rotating in a synchronized manner.
• Operation: Provides smoother airflow and reduced pulsation compared to two-lobe designs.
• Applications: Used where lower noise and vibration are critical, such as in air handling and environmental applications.

**3. Compact ROOTS Blowers

• Design: More compact and space-efficient versions of the traditional blowers.
• Operation: Offers similar performance to larger models but in a more space-constrained design.
• Applications: Suitable for installations with limited space or where a smaller footprint is required.

**4. High-Pressure ROOTS Blowers

• Design: Engineered to handle higher pressures.
• Operation: Capable of generating high pressure with consistent airflow.
• Applications: Ideal for high-pressure pneumatic conveying, industrial processes requiring elevated pressures.

**5. Low Noise ROOTS Blowers

• Design: Incorporates noise reduction technologies.
• Operation: Designed to minimize operational noise.
• Applications: Used in environments where noise reduction is a priority, such as in sensitive industrial settings or residential areas.

**6. Oil-Free ROOTS Blowers

• Design: Operates without the use of oil in the compression chamber.
• Operation: Provides clean air with no risk of oil contamination.
• Applications: Critical for applications requiring oil-free air, such as in food processing, pharmaceuticals, and electronics manufacturing.

**7. Variable Speed ROOTS Blowers

• Design: Equipped with variable speed drives for adjustable operation.
• Operation: Allows for precise control of airflow and pressure.
• Applications: Useful in applications requiring variable airflow and pressure control, such as in dynamic industrial processes.

**8. Explosion-Proof ROOTS Blowers

• Design: Built to meet safety standards for hazardous environments.
• Operation: Designed to operate safely in explosive or flammable environments.
• Applications: Used in industries with explosive atmospheres, such as chemical processing and mining.

Key Considerations for Selection

• Application Requirements: Match the blower type to the specific needs of your application, including flow rate, pressure, and operational environment.
• Noise and Vibration: Consider models with noise reduction features if operational noise is a concern.
• Space and Size: Choose compact models for space-constrained environments.
• Maintenance and Reliability: Evaluate the ease of maintenance and overall reliability of the blower type.

Each type of ROOTS blower offers unique features and benefits suited to different industrial applications. If you need more information on selecting the right type for your needs or have specific requirements, feel free to ask

Maintenance Partners provides services on various types of blowers, for example:

Vacuum blowers

All brands

We offer repairs on blowers of all brands, including Aerzen, Dresser-Rand (Roots) and Ebara.
Blower Services

Our services range from standard inspections and repairs to complete overhauls. A repair or overhaul of a roots blower generally consists of an Inspection, Repair/Modification and a final Report.
Maintenance Partners – Blowers 04Inspection

The first step when repairing a blower is the inspection. Blower inspections include:

Visual inspection
Measuring axial and radial clearances
Measuring of backlash
Disassembly + visual inspection of parts
Dimensional measurements
Blueprint
Oil sampling & check

When the inspection is finished, an inspection report is drawn up with recommendations for repair.
